PERFORATING MACHINE.

Application med June 1, 1920. "Scriai' No.'"385,466.

To all whom it may concern Be it known that I, ALFRE L. DAY, a citizenof'the Unitedfitates, residingat'l roolcline, county of Norfolk, State.oi l'vlassachusetts, have invented an Improvement in PerforatingMachines, cit which the" following description, ,lIrCODHQ'C LlOH withthe accompanying drawing, is a specification, like characters on thedrawing representing like parts.

This invention relates to perforating machines andhas for its principalobject tomechanism will n-eterably be adjustableso that it can he set ateach? actuation to pen tor-ate the nunibers or characters desired.

The invention has the advantage that it obviates thenecessity'or"'introilucing a slip or sheet of paper into the machine. to receive theperforated recordbecause the slips or sheets 'on which thepertoratedrecords are to be made' are contained within themachine andaredelivered automatically as the machine is actuated.

i In order to give an understandingo-fmy invention, 1 have illustratedin the-drawgs a: selected embodiment thereof which will now bede'scribed, after which the novel features will be pointed out in theappended claims. 3 I p In: the drawings, Fig. 1 is a side View of aperforating machine embodying my invention with a portion broken =out toi better show the interiorconstruction; Fig. Qisa t'ront VlLW of Fig. l:i Fig. 3 is a detail view of the trip mechanisin tor controlling theshears Fig. l is aplan viewot' the mechanism shown in Fig. 3;

Fig. 5 is asection on the line5-5, Fig. 4. The devii-eherein showncomprisesabasc frame 1 having; a throat 2 through which .the slipsioi'paper are ejected andalso having a die-plate situated beneaththei-throat and provided-with apertures to-receive punches 4: which aresituated above thethroat and are properly guided '111 their verticalmove ment. The punches are arrangedimgroups, and means are provided forselectively actuating'the punches of each group therebyto perforate anydesired character-in a-slip or sheet oi? paperwhichi'n aybesupported onthe" die-plate 3. Thisselective actuation oE-the punches accomplished bya-matrix memher, as usualinperttorating machines of this type. Iiithemachine isdesigned to perforate a 'pluralityof characterssimultaneously; th en it -W1ll be provided with a 'plural-ityot groupsofpunchesA anda corresponding number of matrix members. i In themachinefshown in, the drawing, there; are, four such; groups of punches,and tourma-trix' members, the latter being;indicated-at ally mounted onashaft 6 carriedin a mov:

a rearward extension 8 which-:is: pivoted'to the baseirame at'9.J'Each'inatrixmember s 5 has the circular tlace 10in which is formed aplurality of groups'otrecesses the recesses of each grouobeing-soarrangedirelative to each other that the-soli d:,.pii rtions; betweenthe recesses represent some particular charber against thepunchesgand'.those punches which'stand opposite "recesses will not bedepressed but will remain; in their eley'ated position whileithe puncheswhich are ope .posite-sol d; portions of the'matrii: willrbe depressedand forced through the die-plate 3 thereby perforating any slip or sheetof paper which may be resting on thedie-plate.

'llhe matrices may be adjus ed iii-any suitable way. Each is hereinshown as havinga circular extension 11' provided with "a thumb-piece 12which extends through aslot 13 in the head and by which. the matrixinaybe turned about the shaft to bringany group of recesses into line withthe punches.

The parts thus far described are or may be all; as illustrated anddescribed iii-my copending, application "Ser. No; 9,162, filed May 5,11920.

In the present embodiment of the invenbeing p ivot ing head 7. Thigheadis shown; as'having;

tion the head 7 is givenits movement by means of an eccentric 14: faston a shaft 15 which is journaled in the base frame 1 and extendstransversely thereof. This eccentric is provided with an eccentric strap16 having an arm 17 which is pivoted to the head at 18. With thisconstruction, each rotation of the shaft 15 will lower the head therebyactuating the punches and thenraise the head again.

.NAssociated with the base frame 1 is a azinejcontaining a plurality ofslips or sheets of paper to be perforated, and means are providedwhereby upon each actuation of the 2 machine one slip will be perforatedand then will be'd-elivered'from the machine.

.'The magazine may be made in various wayswithout departing from theinvention. Perhaps the most convenient form of magazinc is that hereinshown which is in the nature of a roll of paper which is situated withinthe base frame 1 and is constructed so-that at each actuation of themachine a length of paper will be withdrawn from the roll and severedand delivered from the ma chine. 19 indicates a roll of paper which isrotatably mounted on a shaft 20 carried by the base frame. The strip ofpaper 31 from the roll extends through the throat 2 and over thedie-plate 3, and means are provided whereby each timethat the punchesareactuated to perforate theportion of the stri of paper 31 which isover the die-plate 2), the portion of the stripwhich is thus perforatedwill be delivered from the throat-2 and will then be severed from thestrip thereb leaving an unperforated portion of the strip beneath thepunches for the next actuation of the machine.

The feeding of the strip of paper from the roll 19 maybe rovided for invarious ways without departing from the invention. One convenientfeeding device is that shown which comprises the two feed rolls 21 and22 rotatably mounted upon the shafts or pins 23 and24l, These rolls mayconveniently be rubber-covered or have some friction surface se thatthey will have sufiicient frictional e11- ward movement.

. only mesh with the gear 26 while the head is being carried through thelast part of its up- The parts are shown in Fig. 1 in the position theywould assume half of the revolution of the shaft, the head 7' will bedepressed thereby performing the perforating operation and during thelast half of the revolution the head '7 will be eleg vated. hen the headis elevatedabout half-way or has been raised sufficiently to clear thepunches from thepaper, then the gear 25 comes into mesh with the gear26, and during the final upward movement of the head, the roll 21 isrotated thereby feeding the paper forward," and by the time the head iscompletely raised and the shaft is brought to rest in the position shownin Fig. 1, the gear 25 will be just clear from the gear Thesize of thegears and the size of the rolls are so proportioned as to feed the paperthe proper amount before the gear 25 is carried out of mesh with thegear 26.

If desired, the rolls 21 and 22 may be geared together so that both willbe positii' ely rotated.

It is sometimes desirable to have a dupli cate copy of-each perforatedrecord made, and when thisis the case, I propose to employ a. secondroll 28 which is mounted on the shaft 29 and which delivers strip ofpaper 30 through the throat in addition to the strip 31. Both strips ofpaper may pass hetr-Jeen the feed rolls 2i, 22 and thus be fedsimultaneously;

iiy invention also contemplates means for automatically severingfrom thestrips 30 and 31 the portion thereof which has been perforated after theperforation has been made, thereby providing the separate perforatedslip. This severing of the slips from the strip is accomplished by meansof a shear device situated at the delivery'end of the throat 2 andwhich'is actuated just after the paper has been fed forward sufficientlyto eject the perforated portion of'the strips from the throat.

This shear device com prises a fixed shear blade 32 situated above thethroat,'and a movableshear blade 33 which is pivoted to the base at 3%.The blade 33 extends beyond the pivot. as shown at 35, and is acted uponby a spring 36 which tends I to swing it into closed relation with thefixed shear blade 32. v I

Means are provided for automatically opening the shears by swinging theblade 33 downwardly into the dot-ted line position while the paperis-being fed and then re leasing the blade to allow the spring 36 toactuate it to shear off the length. For thus opening the blade, Iprovide a latch 37 which is pivoted to a lug 38 extending from the s deof the head 7 and which operates inia slot 39 formed in the side wall ofthe base 1.

This latch 37 is acted upon by a spring 40 which tends to swing itoutwardly. The lower end of the latch is beveled, as shown at 41, andthe end of the blade 33 is provided with a pin42. When the head movesclownwardly, the beveled portion 41 of the latch 37 engages the pin and,swings the latch backwardly, and by the time the head has completed itsdownward movement, the latch is carried below the pin and is swungoutwardly beneath the pin by the spring 40. As the head rises, the latchby its engagement with the pin 42 will swing the blade into the dottedline position, Fig. 2, thereby placing the spring 36 under increasedtension, and carrying the blade below the mouth of the throat so thatthe strips of paper may be fed forward and delivered therefrom. I

Means are provided for releasing the latch from the pin just at the timewhen the head completes its upward movement thereby permitting thespring 36 to act to close the shears and cut off the perforated lengthsfrom the strips 30 and 31. This is herein accomplished by means of alever 43 pivoted to the frame at 44, and one end of which is adapted toengage the latch 37. The other end of the lever is adapted to be engagedby a beveled arm 45 carried by the shaft 15, and this arm is sopositioned that it will engage the lever 43 just as the shaft 15completes its rotation. The engagement of this arm .45 with the lever 43will swing the lever about its pivot thereby forcing the outer end ofthe lever inwardly toward the frame and forcing the latch 37 backwardlyout of engagement with the pin 42. The engagement of the arm 45 with thelever 43 serves not only to release the latch 37, but also to give theoperator indication as to the proper point at which to stop rotation ofthe shaft l5.- I

The slips which are severed fall onto the platform portion 46 of theframe from which they may be removed by the operator.

I may if desired provide a strip of paper 47 which is wound on reels 48and 49 and on which a record of all perforations may be made. Theportion of the strip of paper between the rolls 48, 49 passes over thedieplate 3 beneath the strips 30 and31, and,

therefore, wheneverthe machine is oper ated, a perforated record will bemade in the strip 47. This strip 47 is fed intermittently so'that thesuccessive perforations will be madeat different places along the Istrip. This feeding of the strip 47 is accomplished by gearing the roll49 to the roll 31 by means of an intermediate gear 50 which meshes withthe gear 26 and also with the gear 51 on the roll 49. Hence at eachfeed-- ing movement of the strips 30 and 31, the

strip 47 will be fed forward.

I claim:

1. In a perforating machine, the combination with perforating mechanismcompris-.

ing a die plate, a plurality of punches, a ver .tically-swinging headcarrying matrices to selectively operate the punches, of a shaft havingan eccentric thereon connected to said head for actuating the latter,and

means actuated by the rotation of said shaft 1 and then to raise thehead again at each rotil-131011 of the shaft, and means operative duringthe last portion of each rotation of the shaft to feed sheet materialinto position to be punched.

4. In a perforating machine, the combina tion with perforatingmechanism, of means to actuate it, means to feed a strip of paper so asto bring different portions of it successively into position to beperforated, a

knife for severing the perforated portions of the strip,means actuatedby the actuating mechanism for the perforating mechanism.

to swing on said knife in one direction, and a spring to give the knifeits cutting movement.

In testimony whereof, I have signed my name to this specification.
